Официальное название

Training Medical Residents in the Use of the Venous Excess UltraSound (VExUS) Score for Bedside Volume Assessment: a Randomized Controlled Trial

Обзор

This randomized controlled trial evaluates the effectiveness of two training approaches (in-person versus remote) for teaching medical residents to apply the Venous Excess Ultrasound (VExUS) score for bedside volume assessment in patients with acute heart failure. Resident performance will be compared to that of expert physicians certified in abdominal and duplex sonography.

Подробное описание

Accurate assessment of volume status is essential in managing acute heart failure but remains challenging in clinical practice. The VExUS score is a validated ultrasound-based tool integrating inferior vena cava diameter and Doppler assessment of hepatic, portal, and intrarenal veins.

This single-center randomized controlled trial compares two training modalities (in-person vs. remote) in medical residents with basic ultrasound skills. Participants will be randomized 1:1 to either training method and compared to a control group of expert physicians.

Primary outcomes include ultrasound image quality assessed using a standardized 100-point score. Secondary outcomes include time to acquisition, VExUS scoring accuracy, self-confidence, and acceptability of training methods.

Вмешательства

• Поведенческое In-person VExUS Training Program
  In-person training consisting of a 1-hour theoretical introduction followed by a 3-hour supervised hands-on ultrasound training session focusing on acquisition and interpretation of the VExUS score.
• Поведенческое Remote VExUS Training Program
  Remote training consisting of an e-learning module followed by independently performed ultrasound examinations with asynchronous expert feedback (via phone or email).
• Другое No intervention
  SGUM-certified physicians performing VExUS examinations as expert reference standard.
